Agilent HCPL-7520

Isolated Linear Sensing IC

Data Sheet

Features

• 15 kV/µs common-mode rejection

at Vcm = 1000 V

Description

Functional Diagram

• Compact, auto-insertable 8-pin

DIP package

The HCPL-7520 isolated linear

current sensing IC family is

designed for current sensing in

drives. In a typical implementa-

tion, motor current flows through

an external resistor and the

resulting analog voltage drop is

sensed by the HCPL-7520. An

output voltage is created on the

other side of the HCPL-7520

optical isolation barrier. This

single-ended output voltage is

proportional to the motor

• 100 kHz bandwidth

SHIELD

• 0.06% nonlinearity, single-ended

• Worldwide safety approval:

UL 1577 (3750 Vrms/1 min.) and

CSA (pending), DIN EN 60747-5-2

(Option #060 only pending)

The product can also be used for

general analog signal isolation

applications. For general

current. Since common-mode

voltage swings of several hundred

volts in tens of nanoseconds are

common in modern switching

inverter motor drives, the HCPL-

7520 was designed to ignore very

high common-mode transient

slew rates (of at least 10 kV/µs).

applications, we recommend the

HCPL-7520 (gain tolerance of

5%). The HCPL-7520 utilizes

sigma delta (Σ-∆) analog-to-

digital converter technology to

delivery offset and gain accuracy

and stability over time and

temperature. This performance is

delivered in a compact, auto-

insert, 8-pin DIP package that

meets worldwide regulatory

safety standards. (A gull-wing

surface mount option #300 is

also available).

• Advanced sigma-delta (Σ-∆)

A/D converter technology

Applications

• Low-power inverter current

sensing

• Motor phase and rail current

sensing

The high CMR capability of the

HCPL-7520 isolation amplifier

provides the precision and

stability needed to accurately

monitor motor current in high

noise motor control environ-

ments, providing for smoother

control (less “torque ripple”) in

various types of motor control

applications.

• Switched mode power supply

signal isolation

• General purpose low-power

current sensing and monitoring

• General purpose analog signal

isolation

CAUTION: It is advised that normal static precautions be taken in handling and assembly of this

component to prevent damage and /or degradation which may be induced by ESD.
